In order to delete ARCHIVE logs which are stored in ASM FLASHDG, which will have a type of "ARCHIVELOG" and "BACKUPSET" i've used this above two queries.After performing this steps , my Active dataguard is not applying archives.

On the primary server, check the latest archived redo log
SELECT sequence#, first_time, next_time
FROM v$archived_log
ORDER BY sequence#;

The alert.log shows receipt of Thread#2 archivelogs only, not Thread#1. Your Primary database is a RAC database with at least two threads. The query on the Primary that you posted seemed to have been on Thread#1 whose archivelogs are not visible at the Standby.
